Open Multilingual Wordnet

This page provides access to wordnets in a variety of
languages, all linked to
the Princeton Wordnet of
English (PWN). The goal is to make it easy to use wordnets in
multiple languages. The individual wordnets have been made by
many different projects and vary greatly in size and accuracy.
This page has (i) extracted and normalized the data, (ii) linked
to it Princeton WordNet 3.0 and (iii) put it in one place. This
page only includes those with a license that allows
redistribution. There is a fuller list at the Global Wordnet Association's
Wordnets
in the World page.

If you use these wordnets, please cite the original projects
who created them (linked in Table 1), if you got value from this
aggregation, please cite Bond and Paik (2012).

For this data to be really useful you need to combine it with the
synset relations from the Princeton wordnet.

Wordnet LMF Files

Wordnet-LMF format files are made by combining the tab files with the Princeton wordnet. Note: individual wordnet projects may have better versions of the wordnet LMF files.

Known Problems

We discard any synsets not linked to PWN (such as new synsets
in the Arabic wordnet). The
Global Wordnet Association (including us) is working to build a better
version that can handle these links.

If the wordnet has a different structure, we only show those
concepts with synonymous or near synonymous links to PWN. So for
Danish, Polish and Norwegian, we only have a small subset of the
entire wordnet.

We currently only make use of synset level sentiment analysis
from ML-SentiCon (Cruz et al., 2014),
we do not show the language specific lemma level analysis.

We currently can't add wordnets that don't link to PWN (such
as Gaelic).

We are focused on adding lemmas, we do not have all extra
information from other projects such as:

Definitions and examples from wordnets such as Spanish

Orthographic variation and pronunciation in the Hebrew Wordnet

We plan to add this information as time permits.

We should strip diacritics from the Arabic wordnet to make it easier for lookup.

We may yet be missing some available wordnets: please help us add
more. Any wordnet with an open license that links to the
Princeton Wordnet is welcome.
